Journal ArticleDOI
3-Nitrooxypropanol Decreased Enteric Methane Production From Growing Beef Cattle in a Commercial Feedlot: Implications for Sustainable Beef Cattle Production
Aklilu W. Alemu,Liana K. D. Pekrul,Adam L Shreck,Calvin W. Booker,Sean M. McGinn,Maik Kindermann,Karen A. Beauchemin +6 more
TL;DR: In this paper, the effects of 3-nitrooxypropanol (3-NOP) on animal performance, health and enteric methane (CH4) production of beef cattle fed a backgrounding diet were evaluated in a commercial feedlot.
Journal ArticleDOI
Recombinant fibrolytic feed enzymes and ammonia fibre expansion (AFEX) pretreatment of crop residues to improve fibre degradability in cattle
Karen A. Beauchemin,Gabriel O Ribeiro,Tao Ran,Tao Ran,Mohammed R. Marami Milani,Wenzhu Yang,Hassan Khanaki,Rob J. Gruninger,Adrian Tsang,Tim A. McAllister +9 more
TL;DR: The authors examined the potential of ammonia fibre expansion (AFEX) technology and dietary supplementation of a preselected recombinant xylanase to improve the in situ degradability of four crop residues for ruminants.
Patent
Use of proteolytic enzymes to increase feed utilization in ruminant diets
TL;DR: In this paper, the authors proposed a method of increasing fiber digestion in ruminants by providing a feed additive or feed composition comprising at least one protease, whereby an increase in digestibility is effected.
Journal ArticleDOI
Prediction of enteric methane production from dairy cows
TL;DR: In this article, the potential for prediction of enteric methane (CH4) emissions from dairy cows by using predicted rumen plus hindgut digested (fermented nutrients) and total tract digested nutrients (by using NorFor) was elucidated.
Journal ArticleDOI
Assessment of the potential of feed enzyme additives to enhance utilization of corn silage fibre by ruminants
Jong-Su Eun,Karen A. Beauchemin +1 more
TL;DR: It is hypothesized that the fermentation of corn silage by a mixed culture of rumen microorganisms in an in vitro system could be increased using exogenous fibrolytic enzyme additives, and that the improvement would depend on the dose of cellulase or xylanase activity provided.
